GROWING PERESKIA The Original Cactus Needs Your Attention Pereskia are really not very well-known plants. Even among succulent lovers, they are certainly not highly prized. The fact they are a significant part of the Cataceae group still does not reward them special attention. Often, botanists will tell you, that they are usually found only in botanical gardens. Yet, they serve as a significant starting point for the debate about the origin of cacti.

Or better still, visit the Saguaro National Park. When young they look some what different from the giant adults. They also need a degree of protection from animals and very extreme weather. When old enough, they produce white waxy flowers in early summer, followed by starling red fruits later. It takes the saguaro many years before they begin to branch. Most of the ones you come across will generally be of one stem, because their survival is never guaranteed.
